FAQ

What is the average rate of change?

The slope of the straight line joining two points on a curve — how much the output changes on average per unit of input.

How is it different from the derivative?

The derivative is the instantaneous rate at a single point, while this measures the average across an interval.

Can the result be negative?

Yes — a negative value simply means the function decreased on average between the two points.

Calculate percentages three ways: what is X% of Y, X is what percent of Y, and Y increased or decreased by X%.

Calculate the percentage increase or decrease between two values, with the absolute difference and direction.

Find the percentage difference between two values relative to their average — the symmetric comparison used in science and engineering.
